# Capture user interactions
> Track in‑app user activity with the Unify Intent client.
export const UnifyLogoLight = () => ;
export const UnifyLogoDark = () => ;
## Overview
User interactions can be used to powerful Plays that drive activation, upgrades,
expansion, and more. By tracking key in‑app events, you can identify and engage
with users based on their actual product usage and behavior.
Some examples of interaction‑based Plays include:
* **Activation Plays** — Target users who clicked on or started using key
features but haven't yet completed the activation criteria.
* **Upsell Plays** — Reach out to users who encountered paywalls or usage limits
to offer assistance or upgrade options.
* **Expansion Plays** — Identify users who are actively using specific features
and target them with relevant cross-sell or upsell offers.
There is no limit to the number or types of interactions you can track. All the
activities you track can be linked to Company, Person, and other object records
in Unify. This gives a complete view of user behavior within the context of your
business.
## Prerequisites
* Ensure you've already installed the Unify Intent client in your application.
See [Set up the Unify Intent client](#setup) for instructions.
* Ensure your users are being identified when they log in. See
[Capture user logins](/developers/guides/product-usage-data/user-logins)
for a walkthrough.
## Examples
Custom events can be used to capture any type of user interaction within your
application. Below are some examples of common use cases and patterns for
recording user activity.
### Feature button clicked
When a user clicks a button to open or use a feature:
```ts theme={null}
unify.track('Created a Widget', {
feature: 'widget-builder',
type: 'gizmo',
number_created: 4,
});
```
### Paywall encountered
When a user hits a paywall or usage limit:
```ts theme={null}
unify.track('Widget Limit Reached', {
feature: 'widget-builder',
reason: 'plan_limit',
current_plan: 'Free Tier',
limit_reached: 10,
number_requested: 20,
});
```
If you present upgrade options, also track the click:
```ts theme={null}
unify.track('Upgrade CTA Clicked', {
destination: 'billing',
source: 'widget_paywall',
plan_selected: 'Pro',
});
```
### User added
When a user invites another user to their account:
```ts theme={null}
unify.track('User Invited', {
added_user_email: 'bob@acme.com',
role: 'Editor',
});
```
